How to reproduce the benchmark results of SGLang
Prerequisite
Install the latest SGLang
git clone https://github.com/sgl-project/sglang.git
cd sglang
git checkout v0.2.7
pip install --upgrade pip
pip install -e "python[all]"
pip install flashinfer -i https://flashinfer.ai/whl/cu121/torch2.3/
Set up ulimit and HF_TOKEN
ulimit -n 65535
# Change the token to a real and usable one, with access permissions for the Llama 3 models.
export HF_TOKEN=hf_token
Launch the server
# Meta-Llama-3.1-8B-Instruct
python -m sglang.launch_server --model-path meta-llama/Llama-3.1-8B-Instruct --enable-torch-compile --disable-radix-cache
# Meta-Llama-3.1-70B-Instruct
python -m sglang.launch_server --model-path meta-llama/Llama-3.1-70B-Instruct --disable-radix-cache --tp 8
# Meta-Llama-3-70B-Instruct-FP8
python -m sglang.launch_server --model-path neuralmagic/Meta-Llama-3-70B-Instruct-FP8 --disable-radix-cache --tp 8
Benchmark
Hardware Requirements
- 8B models: Single NVIDIA A100 80GB GPU
- 70B models: 8 x NVIDIA A100 80GB GPUs with Tensor Parallelism (TP) 8
- 70B FP8 models: 8 x NVIDIA H100 GPUs with Tensor Parallelism (TP) 8
Please ensure you have the appropriate hardware before running the benchmarks.

We tried using vLLM 0.5.3.post1, but it often crashes under high loads, and it seems to have similar or worse performance compared to vLLM 0.5.2 from our partial benchmarking, so we are using the older version, vLLM 0.5.2.
For TensorRT LLM preparation, follow your internal TensorRT-LLM deployment guide. Specifically, we used a batch size of 512, a max input length of 8192, and a max number of tokens of 8192. The instance count for preprocessing and postprocessing in Triton Server is 16.
